What is the primary goal of machine learning?
Correct!
Wrong!
Machine learning allows systems to learn patterns from data and make decisions or predictions without being explicitly programmed for each task.
Which of the following is a supervised learning algorithm?
Correct!
Wrong!
Decision Trees are a common supervised learning algorithm used for classification and regression tasks.
In machine learning, what is "overfitting"?
Correct!
Wrong!
Overfitting occurs when a model learns the training data too well, capturing noise and irrelevant patterns, leading to poor performance on unseen data.
What is the purpose of cross-validation in machine learning?
Correct!
Wrong!
Cross-validation is a technique used to assess how a model will generalize to new data by partitioning the dataset into training and validation subsets.
Which type of machine learning algorithm is commonly used for clustering?
Correct!
Wrong!
K-Means is a popular unsupervised learning algorithm used for clustering data into groups based on similarity.
